Amanda Seyfried Talks Big Boobs, Lindsay Lohan and Singing!

The "Les Miserables" star covers the May issue ofallure magazine where she gets pretty darn candid about her cleavage and acting roles.

Amanda is definitely fortunate (in more ways than one) but hey, at least the girl appreciates what she's been given ... although she hasn't always been so grateful.

Seyfried tells the mag, "I saw a picture a couple of days ago from when I was 19, and my boobs were way bigger. They were a D, and now they're a small C, because I lost weight."

"There was something so beautiful about the size of them. When I look back, I'm like, 'Why did I always give myself such a hard time?," she says.

But being busty can pose it's own (painful) problems: "They do get in the way a lot. Like, I wear a really small, tight sports bra when I go running . . . because they want to smack my chin."

The 27-year-old also opens up about her former "Mean Girls" costar, Lindsay Lohan, and the possibility of a Broadway adaptation of the popular flick.

And, if "Mean Girls" makes Broadway, Amanda is on board: "I desperately want to be Regina," she tells the mag.

Amanda also talks about LiLo, who at the time (when they worked together) she had a lot of admiration for. "She's talented," pauses, "Was." Another pause. "I mean, I don't know.... She was so bright-eyed," Seyfried tells the mag.

The blonde beauty is pretty outspoken, admitting she has no filter when she talks. Sharing how she trained for "Les Mis," Seyfried says she used her role in "Deep Throat" (playing porn star, Linda Lovelace), to help her prepare.
